Every time I restart my PC, I get in the grub rescue> prompt, just because before that I accidentally deleted a volume with my linux distro, including grub(my PC is dual-bootable). Using some external tools, I restored the partition, and its number changed from 6 to 4.
The problem is that every time I boot my PC, I need manually run such commands as
set prefix=(hd0,4)/boot/grub set root=(hd0,4) because as I said, previous number of partition was 4 instead of 6, and PC do not save this information.

Try to update grub configuration.
On Ubuntu or similar: update-grub
On Fedora or similar: grub2-mkconfig -o /boot/grub2/grub.cfg
